     原理：1.把所有的li的高度值放到数组里面
     2.第一行的top都为0
     3.计算高度值最小的值是哪个li
     4.把接下来的li放到那个li的下面

    var li=$("li");//这里是区块名称
    var	li_W = li[0].offsetWidth+margin;//取区块的实际宽度（包含间距，这里使用源生的offsetWidth函数，不适用jQuery的width()函数是因为它不能取得实际宽度，例如元素内有pandding就不行了）
    function liuxiaofan(){//定义成函数便于调用
        var h=[];//记录区块高度的数组

                h[minKey] += li_H+margin ;//加上新高度后更新高度值
                li.eq(i).css("top",min_H+margin);//先得到高度最小的Li，然后把接下来的li放到它的下面
